COKE-HANDLING APPARATUS.

Original application filed April 23, 1920, Serial No. 376,126. Divided and this application filed April 18,

This invention relates to coke handling apparatus, .and has for its object to provide means for quenchingthe hot coke as soon as it is discharged from the colring chambers, such as retort colte ovens, without resort to expensive quenching car apparatus for carrying the coke away to quenching stations, as commonly employed; to provide conveyer means for carrying the colte away, as vsoon as itA is quenched, and also to provide for discharging the water employed in the `quenching in such manner as to substantially prevent the discharge of water on to Vthe conveyer means. n

vIn addition to the general objects r-ecited above, the invention has for' further objects such other improvements or advantages in construction and operation as are found to obtain in the `structures and devices hereinafter described or claimed. y y

th-e invention; features of construction and operation are, however, capable of other valuable applications, for example, to colting plants of whatever magnitude. Con-A sequently the invention is not confined in its scope to the specific use and speciiic embodiment herein described as an illustrative example.

Referring to the drawings, there are illustrated sectional views ot a coke oven battery or plant of the luy-product type, such as has been hereinbetore mentioned. The coke oven battery or plant embodies 'in its construction .a plurality ot crosswise elongated heating walls 11, 11 and a. plurality of intermediate crosswise elongated horizontal colring chambers or ovens 12, 12. The heating' walls 11 form the side walls of the respective colring chambers 12, as .shown more particularly in Fig. 3. The coal to be coked is elevated by means of an elevator indicated generally at 15 into the coal hoppers 16 which are supported by a superstructure above the top of the battery olf ovens or retorts 12. Running on a traclr 17 on the top of the oven battery is a larry car 18 which receives coal from the hoppers 16 and charges the several Cokin-g chambers or ovens 12 through charging holes 19 located in the top 20 of the oven battery and positioned directly above the ovens or chambers 12. These charging holes 19 are equipped with the usual removable covers, which are removed durin charging of the several ovens and place in position to vclose thetops of the ovens during the entire coking operation.

`in the severall ovensv or chambers rived'lfrom the lined' heating walls l1,s vhi'eh,Y

as before mentioned, extend crosswise of the battery at the sides of the colring chambers. The crosswise regenerators 2li of the retort. ovenl or battery are located at a. lower levei than the aforesaid heating` walls ll and colting chambers l2 and in the present instance extend in. parallelism beneath the colring;` chambersl and between theV pillar walls 13. The interior meeting ends oi" the regenerators are separated by a partition 25 which extends below the middle lengthwise line. ot the heatingwalls and all the way up. from the mat of. the battery to the bottom of the overlying colingchamber and troni one to the other oithe pillar walls i3'. Each regenerator 24;. is a chamber containing` open bricltworlr commonly called checlrerworlr andindicated at 26 with a distributing sole channel 2?) underneaththe cheekerworlc of each regenerator, the channels tor-ming the soles` 0:5v and opt-mine,` up into the checkerworlr of theirrespecti-ve regenerators. These regenerators in alternation are heated by the hot combustion products that are exhausted from the iiame or combustion tlues hereinbefore mentioned and their impart such heat to the medium` that they feed intoV these flame fines. The regenerators are communicably connected with the fines by ducts 4.9, and operate in conjunction therewith' as tullyexplained. inV my said co-pendingl application Serial No. 376,126.

On the pusher side A or" the battery, there is provided a pushing machineV 79 of any preferred construction, which pusher machine operates in the usual way to push the charges oi' nished colte from the horizontal coking chambers l2 at the ends of the coking' periods in such chambers, It. will be understood that the doors at both ends ot each colring chamber are removed just prior Y to the pushing operation.

In accordance with the` invention, the hot coke falls through the colring chamber opening-on the coltev side B ot the battey and n directly on to an inclined` coke wharf 8O that extends downwardly from approximately the iioor level of the several colinfg` chambers. OnA this wharf, the. hot colte is di rectly quenched byv water supplied. #from a hose- 8l connected with any suitable source of water supply, and operable from a platform 89 extending;` along' the lower end of the Wharf 80. At the` lower end of the colteV quenching'. and discharge wharf or chute 8O is an endless conveyer 821 which is adapted to carry away the freshly quenched coke for thev usual subsequent handling.. Before and.- duringV the` quenchingoperation, the colte is prevented. from falling` on. to the upper run of the conveyer by means of a pivoted. gate which is adapted to close.

the lower of. the aforesaid wharf or chante SQAk thusseryes to. regulate-the passage of coke from the ook@ Wharf. The

adapted., to wharf,

Lrate S3 is provided with an operating lever 84 permitting,r it to be opened and closed required. As shown in Fig. 3, the gates 83 may be disposed in series extending' alone` the battery, ot a size convenient for handling;` by their respective levers Si. Each gate is Jformed ot reticular material as commonly employed. in colte wharf constructions to permit the passage oit water ironl the lower end ot the wharf S() while the colte is held on the wharf by the gate. 3e.- neath each gate 83 is a defiectinfi' apron 8f3 pivoted at 86 and adapte-:l to be operated by suitable means 87 consisting,- oli u link 90 pivotaliy connected at 91 to an arm O2 that is rigidly secured at 93 to the apron pivot means Tie other end of said link 9() is ivotally connected. at 95 to an arm 9G that is rigidly secured at 97 to shatt 98 that is operated. by the lever 8d. One end of said apronv is iangred at 99 and tue flanged end is arranged, when in the position shown in dot ted lines in Figs. 2 and 3, to terminate into close proximity 100 to the conveyor to prevent. too ,great ar fall of the fresh colte onto the conveyer and thereby minimizing fracture oithe coke. rThe dei'lectingiv aprons 85' may also be extended in series along; the side of the battery and oi' such size as operating' conditions and practice require. then the gate is opened, the apron 85 is automatically and simultaneously swungl into the position indicated by dotted lines in Figi'. 2 so that it acts as a bridge or guide ttor directing? the coke 'from the lower end of the wharf 80 on to the conveyor 82. Yfhen the Lgatev is closed, the apron 85 is automatically an'd simultaneously swunrY to the position indicated by full linesin said figure. to act as a guide for directing' the water that discharges ott the lower end ot' the wharf S() into a discharge trough 8S located beneath the lower end. oi said chute and between the lower end of the chute and the conveyor 82. This construction causes the water employed in the quenching' operation to be discharged into a trough that is located on the coke side of the conveyor and substantially prevents the water from discharging' on to the conveyer.

The invention as hereinabove set forth is embodied in a particular form oi construe tion but may be variously embodied within the scope of the claims hereinafter made.
